GLAZING SYSTEM.

Specification of Letters Patent.

Patented May 10, 1921.

Application filed March as, 1919. Serial ire/285,296.

/ This invention relates to glazing systems of the kind in which'thesheets of glass are retained in position on a reinforced concreteglazing bar without the use of putty or the like and the said inventionhas for its object to provide-improved means for holding the sheets ofglass in position.

According to this invent on tliesheetsof glass are retained in positionagainst a reinforced concrete glazing bar hav ng two upper reinforcingmembers by retaining or securing means adapted to engage metal oli isembedded in the glazing bar and suitably connected to the saidreinforcing mein hers. Each sheet of glass is preferably retained inposition against twp separate and independent bearing surfaces, the saidbearing surfaces being supported by the glazing bar. The retaining orsecuring means comprises a screw, bolt or equivalent passed through. ametal washer and a weather resistii'ig washer on the upper faces oi theglass sheets and adapted to engage a metal clip bedded in the glazingbar and connected. to the two upper reinforcing incinb'ers thereof, alongitudinally disposed strip of bituminous felt or other weatherl'8S1Sting packing being interposed between the lower faces of the glasssheets and the upperface of the glazing bar. The glazing bar is providedwith a centrally arranged plane upper surface adapted to support theflat strip of weather resisting packing such as bituminous felt or othermaterial, a channel or gutter and a recess on each side thereof, thesaid recess being adapted to receive asbestos or like packing material.If de'- sired the centrally arranged plane upper surface of the glazingbar may be extended upwardly so as to be flush or approximately flushwith the {upper faces of the glass sheets.

In order that the invention may be clearly understood, reference is madeto the accompanying drawings whereon Figurel shows a vertical section ofa construction n accord ance with the present invention, Fig. 52%

shows a vertical section of a modified con,

struction also in accordance with the. pres ent invention.

3, 4 and 5 are respectively a side view an end view, and a crosssectionof a modified construction of the glazing .bar and the retainingmeans shown in Fig. 1. Referring to Fig. 1 of the drawings, lie aconcrete glazing bar having two upper reinforcing members 2, 3 and alower reinforcing member 4: of iron, steelor other face of the clip isflush or approximately.

flush with the plane face 5 of the concrete glazing bar.

The clip 13 is formed or provided with two downwardly extending prongslfi, 16 the ends of which are bent, or twisted around the upperreinforcing members 2, 3

The upper face of the of the concrete glazing bar, the lower re- 1inforcing member t being suitably connected. as by stirrups 17 to themembers 2, 3. Thev uppe part of the glazing bar and centrally thereof,is formed with a hole 18 which is intended to receive'the end of a setscrew 19, bolt or equivalent, the said set screw engaging the tappedhole in the clip 13 and thus binding the sheets of glass 20, Elbetweenthe asbestos packings 11, 12, bituminous felt strip 6 and a. bituminousfelt washer 22 overlying the glass sheets. 23 is a metallic washerplaced between the head of the set screw 19 and the washer 22.

In the construction shown in Fig. 2 the central portion of thereinforced concrete glazing bar is extended upward so that the planeface 5 may be flush or approximately flush with the upper faces of theglass sheets, the use of the longitudinally disposed bitumastic feltstrip 6 shown in Fig. 1 being thereby obviated and the bituminous felt35, 36 of th is cast or mol 21 of glass in position is or are made ofasphalt, a mixture of asphalt and tar or similar material or concrete,compressed paper-pulp, imitation marble or stone or other suitablematerial reinforced longitudinally or vertically with'single wires orwith two or more stranded wires as shown at 25. I cap or cover plate maybe formed as a circular, square, rectangular or oblong plate and may bein lengths or sections. In a convenient form and as shown more ticularlyin Figs. 3 and 5, the asphalt plate 24 is of any suitable length and maybe provided with a portion of suitable shape projecting from the lowerface of the cap 24. The metal wires 25, 26 or stranded metal wires areembedded in the asphalt at suitable distances apart, such wires being,if so desired, but not essentially interconnected by metallic or othersuitable bindin material 27 shown dotted in Fig. 5. If deslightly belowthe said surface. The lengths or strips of asphalt 24 are secured to theglazing bar 1 preferably by screws 30 adaptec to engagenuts 3l'embe'ddedin the glazing bar 1 and cast or molded therewith. A

washer 32 or washers of any suitable material may be interposed betweenthe head of each screw 30 and the'length 24 or strip of reinforcedasphalt. 7

At, suitable intervals along each inclined side of the lazing bar,recesses 33, 34 are provided, t e recesses being preferably formed inthe lazin bar 1 when the latter did. he recesses 33, 34 may of anysuitable depth, the characteristic feature of the recesses being thatthe faces e recesses 33, 34 against which the brackets 37, 38 abut arevertical so as to avoid'the use of angled or set-back brackets ortapered distance or filling pieces between the brackets and the glazingbar. At its lower end each recess may be flush with tie lowercorresponding edge of the bar shown more particularly in F ig. 5 and therecesses may be longer as shown in Fig. 3, respective brackets so as toallow for adjustment of the brackets relative to the bolt holes 39 whensecuring the brackets and glazing bar 1 to the purlins 40 or equivalent.A plurality of bolt holes may be provided in the glazing bar 1. at eachrecess to allow for adjustment of the bracket. Each of the brackets 33,34 may be secured by a separate bolt and nut but it is pre ferred thatopposed brackets as secured by the same bolt 41 and nut 42.

' laim is:

1. T 1e combination of a reinforced glazing bar, of glass sheetssupported thereon, and means forming a fixed part of said barand'secured to the reinforce member thereof to retain the glass sheetsin position.

In combination, a reinforced concrete glazing bar, having spacedindependent bearing surfaces for each sheet of glass, 2- member embeddedin said bar and connected h the reinforc ng means thereof, cover centglass c and threaded into said member.

The combination with a reinforced concrete glazing bar, having spacedbearing surfaces to support glass sheets, a member embedded in said barand tied to the reinforce means thereof, cover plates to overlie theglass sheets and bridge the joint between them and a bolt passed throughsaid cover plates between the glass sheets and threaded into said memberto secure the glass sheets in position.

In testimony whereof I have hereunto signed my name.
